Hey guys like the title says is there any advantage using 10mm over the 4mm stuff?? Only reason I ask is that I've had a 4mm od pneumatic air kit sitting around for the longest time that was gonna be used for something else but figured I'd ask you pros first. Any opinions are greatly appreciated. Thanks guys

Oh this is going on my 91 Z28 with a forged 370, 4l80e circle d converter 258mm pro billet, MWC fab 9", VS racing billet 80mm T6 turbo, dominator ECU

I'll put some pictures up with what I've got

 

I’d venture to say the vast majority of people run push lock air line like you’ve got there in the 1/4” (6mm) variety.

 

Yea that's pretty much all I've seen too but how much difference could 2mm make?? Faster response maybe??

 

I think technically you’re correct with that assumption. I doubt in execution you’ll notice the difference in response. The stuff is cheap and easy to work with. Run what you have, if it’s a boost oscillating nightmare or something maybe go to 1/4”. No harm in trying through.

 

I run 1/4 OD tubing. Make sure what you're using is Nylon or PTFE.

Also, the larger tubing ID will likely have better wastegate response.

 

Will make no noticeable difference IMO. I’d use whatever I had…

 

I work with pneumatics alot. Only reason I can see to move to the larger diameter is if you needed a larger volume of air. Say you where trying to fill a 15 gallon tank to 60 psi with an inlet pressure of 100 psi. A 10mm hose will fill it much faster then a 4mm hose. In the volumes of air your talking about in a turbo control system I don't really think you would see a difference in one over the other.

 

Awesome thank you guys for the input!!
